at home. Abc's george stephanopoulos sat down with president obama today for an exclusive interview. The president opening up about a story inhe news that has touched him and his family. The first lady, along with other familiar names, appear to be the victims of a hackattack. Abc's senior justice correspondent pierre thomas has been tracking this story all day. And first things us the latest. Reporter: This sinister looking website is posting what hackers claim is the social security number and credit report of the first lady. The fbi and secret service are investigating and today president obama would not say if the information is authentic, but confirmed authorities are trying to find out what happened. We should not be surprised that if you have hackers who want to dig in and devote a lot of resources, that they can access people's private information. It is a big problem. Right into the white house? Again, I'm not confirming that that's what happened. You got websites that sell people's credit cards that have been stolen. Reporter: Michelle obama is not the only potential victim. Those tarlgetted are a curious mix of the powerful and famous. Vice president biden, former secretary of state hillary clinton, beyonce, kim kardashian. The fbi director and l.A.'S police chief. Tonight ek qui fax confirmed that unauthorized and fraudulent access occurred involving four high profile people, but they declined to identify them. Law enforcement officials are trying to determine how much of the information on the website is authentic and how it might have been obtained. Pierre thomas, abc news, washington. Thank you, pierre. Now we want to bring you more from george's interview, because the president also weighed in on the budget battle, heating up today. Paul ryan today put forward his budget and said he's challenging you to put forward a budget that reaches balance. Are you going to do that? No. My goal is not to chase a balanc balanced budget just for the sake of it. My goal is to put people back to work. If we do that, we'll bring in more revenue, if we control spending and have a smart entitlement package, then potentially what you have is balance, but it's not balance on the backs of the poor, the elderly, students who need student loans, families with disabled kids. That's not the right way to balance our budget. A reminder that you can see more of george's interview with president obama tomorrow morning on "gma."
